// default mongodb
yiigo.Mongo().Database("test").Collection("numbers").InsertOne(context.Background(), bson.M{"name": "pi", "value": 3.14159})

SQL Builder

😊 为不想手写 SQL 的你生成 SQL 语句，用于 sqlx 的相关方法；

⚠️ 作为辅助方法，目前支持的特性有限，复杂的 SQL （如：子查询等）还需自己手写

builder := yiigo.NewSQLBuilder(yiigo.MySQL)

Query

builder.Wrap(
    yiigo.Table("user"),
    yiigo.Where("id = ?", 1),
).ToQuery()
// SELECT * FROM user WHERE id = ?
// [1]

builder.Wrap(
    yiigo.Table("user"),
    yiigo.Where("name = ? AND age > ?", "shenghui0779", 20),
).ToQuery()
// SELECT * FROM user WHERE name = ? AND age > ?
// [shenghui0779 20]

builder.Wrap(
    yiigo.Table("user"),
    yiigo.WhereIn("age IN (?)", []int{20, 30}),
).ToQuery()
// SELECT * FROM user WHERE age IN (?, ?)
// [20 30]

builder.Wrap(
    yiigo.Table("user"),
    yiigo.Select("id", "name", "age"),
    yiigo.Where("id = ?", 1),
).ToQuery()
// SELECT id, name, age FROM user WHERE id = ?
// [1]

builder.Wrap(
    yiigo.Table("user"),
    yiigo.Distinct("name"),
    yiigo.Where("id = ?", 1),
).ToQuery()
// SELECT DISTINCT name FROM user WHERE id = ?
// [1]

builder.Wrap(
    yiigo.Table("user"),
    yiigo.LeftJoin("address", "user.id = address.user_id"),
    yiigo.Where("user.id = ?", 1),
).ToQuery()
// SELECT * FROM user LEFT JOIN address ON user.id = address.user_id WHERE user.id = ?
// [1]

builder.Wrap(
    yiigo.Table("address"),
    yiigo.Select("user_id", "COUNT(*) AS total"),
    yiigo.GroupBy("user_id"),
    yiigo.Having("user_id = ?", 1),
).ToQuery()
// SELECT user_id, COUNT(*) AS total FROM address GROUP BY user_id HAVING user_id = ?
// [1]

builder.Wrap(
    yiigo.Table("user"),
    yiigo.Where("age > ?", 20),
    yiigo.OrderBy("age ASC", "id DESC"),
    yiigo.Offset(5),
    yiigo.Limit(10),
).ToQuery()
// SELECT * FROM user WHERE age > ? ORDER BY age ASC, id DESC OFFSET 5 LIMIT 10
// [20]

wrap1 := builder.Wrap(
    Table("user_1"),
    Where("id = ?", 2),
)

builder.Wrap(
    Table("user_0"),
    Where("id = ?", 1),
    Union(wrap1),
).ToQuery()
// (SELECT * FROM user_0 WHERE id = ?) UNION (SELECT * FROM user_1 WHERE id = ?)
// [1, 2]

builder.Wrap(
    Table("user_0"),
    Where("id = ?", 1),
    UnionAll(wrap1),
).ToQuery()
// (SELECT * FROM user_0 WHERE id = ?) UNION ALL (SELECT * FROM user_1 WHERE id = ?)
// [1, 2]

builder.Wrap(
    Table("user_0"),
    WhereIn("age IN (?)", []int{10, 20}),
    Limit(5),
    Union(
        builder.Wrap(
            Table("user_1"),
            Where("age IN (?)", []int{30, 40}),
            Limit(5),
        ),
    ),
).ToQuery()
// (SELECT * FROM user_0 WHERE age IN (?, ?) LIMIT ?) UNION (SELECT * FROM user_1 WHERE age IN (?, ?) LIMIT ?)
// [10, 20, 5, 30, 40, 5]

builder.Wrap(Table("user")).ToTruncate()
// TRUNCATE user

Insert

type User struct {
    ID     int    `db:"-"`
    Name   string `db:"name"`
    Age    int    `db:"age"`
    Phone  string `db:"phone,omitempty"`
}

builder.Wrap(Table("user")).ToInsert(&User{
    Name: "yiigo",
    Age:  29,
})
// INSERT INTO user (name, age) VALUES (?, ?)
// [yiigo 29]

builder.Wrap(yiigo.Table("user")).ToInsert(yiigo.X{
    "name": "yiigo",
    "age":  29,
})
// INSERT INTO user (name, age) VALUES (?, ?)
// [yiigo 29]

Batch Insert

type User struct {
    ID     int    `db:"-"`
    Name   string `db:"name"`
    Age    int    `db:"age"`
    Phone  string `db:"phone,omitempty"`
}

builder.Wrap(Table("user")).ToBatchInsert([]*User{

        Name: "shenghui0779",
        Age:  20,
    },
    {
        Name: "yiigo",
        Age:  29,
    },

// INSERT INTO user (name, age) VALUES (?, ?), (?, ?)
// [shenghui0779 20 yiigo 29]

builder.Wrap(yiigo.Table("user")).ToBatchInsert([]yiigo.X{
    {
        "name": "shenghui0779",
        "age":  20,
    },
    {
        "name": "yiigo",
        "age":  29,
    },
})
// INSERT INTO user (name, age) VALUES (?, ?), (?, ?)
// [shenghui0779 20 yiigo 29]

Update

type User struct {
    Name   string `db:"name"`
    Age    int    `db:"age"`
    Phone  string `db:"phone,omitempty"`
}

builder.Wrap(
    Table("user"),
    Where("id = ?", 1),
).ToUpdate(&User{
    Name: "yiigo",
    Age:  29,
})
// "UPDATE user SET name = ?, age = ? WHERE id = ?"
// [yiigo 29 1]

builder.Wrap(
    yiigo.Table("user"),
    yiigo.Where("id = ?", 1),
).ToUpdate(yiigo.X{
    "name": "yiigo",
    "age":  29,
})
// UPDATE user SET name = ?, age = ? WHERE id = ?
// [yiigo 29 1]

builder.Wrap(
    yiigo.Table("product"),
    yiigo.Where("id = ?", 1),
).ToUpdate(yiigo.X{
    "price": yiigo.Clause("price * ? + ?", 2, 100),
})
// UPDATE product SET price = price * ? + ? WHERE id = ?
// [2 100 1]

Delete

builder.Wrap(
    yiigo.Table("user"),
    yiigo.Where("id = ?", 1),
).ToDelete()
// DELETE FROM user WHERE id = ?
// [1]

ORM 推荐 ent 的理由是啥, 我们现在在用 gorm,与之比较呢?

gorm:
db.Where("name = ?", 1).Find(&users)

ent:
client.User.Query(user.Name("xyz")).All(ctx)

以前也用 gorm，类型信息全没了，实在不爽。

我习惯用 gorm，看个人习惯了

yiigo，和 yii 什么关系？

@alinwu05 没啥关系，就是用的他的谐音和通“易”的说法，旨在对新手来说，让 Go 开发更容易
